How to repair my GE model JNM1731DM1WW microwave?

The surface light,clock,vent fan,and numbers 3,4,7,8 and 9 do not work....the time cook mode works OK as long as none of the above numbers is used....the oven works fine but is inconvenient to use because of the limitations. Our bldg was struck by lightning prior to these problems, so perhaps there was a power surge....any help would be greatly appreciated.
